From 1db49be03f1a4fa7262d843816c27a77fb90119d Mon Sep 17 00:00:00 2001 From: Brian Zalewski Date: Sat, 20 Jun 2026 23:52:52 -0400 Subject: [PATCH] =?UTF-8?q?fix:=20generate=20the=20favicon=20set=20(was=20?= =?UTF-8?q?5=20dead=20refs=20=E2=86=92=20404=20on=20every=20site)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit index.html referenced favicon.ico, favicon-16/32.png, apple-touch-icon.png, safari-pinned- tab.svg — none existed in public/ (caught by validate-assets, PR #1). Every cloned site shipped 404'd favicons (violates checklist #23). scripts/generate-favicons.mjs generates the full set brand-colored from _brand.json (brandHue → HSL→RGB) with ZERO external deps — pure node:zlib for valid RGBA PNGs (rounded square), a BMP/PNG-in-ICO writer, and SVG (rich, brand bg + business initial) + safari mask. Wired into prebuild so it regenerates per brand and vite copies public/ → dist/. Also added an SVG-favicon (modern browsers). Committed brand-default placeholders so the repo is clean even before a per-brand rebuild. Verified on a clean build: all 6 favicons land in dist/, 0 dead refs, valid PNG/ICO magic bytes. validate-assets (PR #1) now passes the favicon gate.
